Take a deep breath and ignore people suggesting changes. Apart from learning to better control the metal so it doesn't splash, you are doing about right.
this metal is for organ pipes and it needs to be tapered in thickness as well as different alloys. This one is high lead. 97 % lead and 3% tin including trace elements of antimony, bismuth and copper. No place I can buy this anywhere in this form.
OK, the thickness taper is the deal breaker for just going out & buying it. Even if you could get the alloy you'd need a CNC rolling mill to get the taper. Casting it like that is an elegant solution.
Whats the table made of? Something with a high coefficient of heat transfer to set the metal quickly and stop it pooling at the low end?
The table is a one piece 6 inch thick and 14 feet long granite slab. Very nice piece of stone that was cut in Los Angeles for me. On top of the slab is a nomex cloth that can stand the heat. The cloth expands and contracts with the heating and cooling, which can be a problem. this method of casting has been used for hundreds of years. Also sand casting has been used.
I take it the metal would eventually stick to the granite if there were no cloth? How about using something like Foseco Dycote? Too expensive for the given surface area? Might last a while though as its designed to take aluminium and you're casting lead.
the metal wouldn't stick to the granite. The problem without the cloth is that the metal pools. the cloth keeps things in place. But the cloth wears out from the friction of the casting box as well as the metal sticking to the cloth in general.
I am not familiar with Foseco Dycote. Is it a liquid or paste?
Any progress in improving things are always welcome. We have cast metal like this for twenty years. Perhaps four or five times a year. Every time is different.
Its a liquid you spray on but you need to pre-bake it at 180 - 250C (depending on which one you use) before use. That might be an issue. Now that I think about it you could use Molybdenum based ejector pin lubricant. It goes on like grey paint.

Thanks for your kind comments. I like it when people are concerned about my well being.

Short sleeves and no face shields? OSHA would have a few comments on the matter. Bedient's video shows a safer method of production.

What is the smallest thickness (or gauge) of the metal that you cast?
punkorganist 3 years ago
the thinnest metal we cast is about 0.4 mm which is about a 1/128th of an inch. The thickest is about 5 mm or close to a 1/4 inch

It has something to do with what sound one is looking for. brighter sound with high tin and mellower sound with high lead content. (simply speaking)

Why some organ builders prefer alloys with high percentage of thin than lead?
HumbertoMarquez 3 years ago
that looks absolutely beautiful, make some more videos of how these are formed into pipes and tuned!

What kind of metal is this? I take it they can't just buy sheets of it or they'd not be going to all this bother.

Wonderful! I'd love to see some more videos of this marvelous art!

I hope we'll be seeing more organ building videos in the future... This could be a very important educational "ministry," for you, Mr. Pasi.
